The Anthony Cummings-trained Stray got off the mark at the sixth attempt when winning at Randwick on Wednesday.
After what Cummings felt was a luckless debut campaign, Stray could now be Australian Oaks bound and is a 16/1 shot for the Group 1 feature on 9th April.
A daughter of Thunder Fantasy, Stray's first preparation saw her tackle the Listed Dulcify Stakes, Group 3 Gloaming Stakes before ending the campaign with a midfield finish in the Group 1 Flight Stakes.
Sent off as the well-supported $3.20 favourite for Wednesday's contest, the three-year-old was sharp away from the barriers under Jason Collett and travelled well behind the leaders.
Coming home three-wide round the bend, the filly careered away from her rivals to win by just over two and a half lengths at the line.
"She's very good, it's hard to put it in any other terms," Cummings said. "She was almost arrogant there in the finish and she's still got a lot of improvement left in her.
"She had no luck at all (debut preparation) - barriers and different things. She should've beaten Profondo first-up which would've been good form leading into anything as the carnival unfolded. I think the things we are looking at for this preparation are well within her reach."
Having ridden Stray in a Randwick trial placing, Collett was full of confidence going into the first-up assignment.
"We were pretty confident coming into today in this sort of field that she should be able to put them away," Collett said.
